PSR vs Annual Rack Inspection: What Ontario Warehouses Keep Getting Wrong
PSR vs annual rack inspection is one of the most misunderstood topics in Ontario warehousing. Many facilities assume they are compliant because they had an inspection or received drawings years ago. However, the Ministry of Labour cares about two things. Your racking must be certified before use, and it must be maintained during use.

A PSR, a PSR exemption, and an annual inspection are three different documents. They do not replace each other. This guide explains what each one means and how they fit into Ontario’s compliance system.
1. What a PSR Is and Why Ontario Requires It
A PSR, or Pre Start Health and Safety Review, is an engineering review required under Ontario Regulation 851, Section 7. The regulation lists racking systems under Item 3. As a result, many new or modified racking installations require a PSR before they can be used.
Here is what a PSR includes:
- Review of your design to a recognized standard such as ANSI MH16.1
- Verification that your installation matches the drawing
- Checks of anchorage, guarding, and load application
- A sealed engineering report from an Ontario P.Eng
If you need help determining whether your system requires a PSR, you can refer to our compliance page:
Rack Safety and Compliance.
When a PSR is required
- New racking
- Relocated racking
- Reconfigured beam elevations
- Changes to capacity or layout
- Mixed brand or used components
- Repairs that affect structure
What a PSR is not
- It is not a drawing
- It is not a one page letter
- It is not a sales document
- It cannot be reused for layouts that no longer exist
If your racking does not match the certified configuration, the PSR is not valid.
2. PSR Exemption Letters and When They Apply
A PSR exemption letter is allowed under Ontario’s PSR guideline. It applies when a racking system is designed to a current standard and is installed exactly as documented. In this case, a facility may use a PSR exemption instead of a full PSR.
A proper exemption package includes the following items:
- A sealed letter from a P.Eng confirming ANSI MH16.1 compliance
- Manufacturer documentation such as capacity tables and installation instructions
- Verification that the installation matches the drawings
Common mistakes include using letters from unrelated projects, treating sales emails as certification, changing beam heights after installation, or mixing used components. These mistakes remove the system from exemption eligibility.

3. Annual Rack Inspections and Why They Do Not Replace Certification
Annual rack inspections are required under CSA A344. They apply to racking that is already certified. These inspections evaluate the condition of the system and help identify damage early.
Annual inspections typically include the following checks:
- Frame and column damage
- Beam impact or deformation
- Missing safety clips
- Loose or missing anchors
- Out of plumb conditions
- Unauthorized reconfigurations
- Component incompatibility
Annual inspections do not certify a system. They do not confirm load capacities. They do not validate design. They only assess the current condition of the system as it exists today.
As a result, a perfect annual inspection report on a system that was never certified still leaves the system uncertified.
4. The Correct Ontario Compliance Workflow
Here is the workflow every Ontario warehouse is expected to follow. This is the simplest way to understand how a PSR, a PSR exemption, and an annual rack inspection fit together.
Step 1. Certification Before Use
- Obtain a PSR or
- Obtain a PSR exemption
Step 2. Commissioning
- Verify installation against drawings
- Install load signs
- Store documentation onsite
Step 3. Ongoing Inspections
- Perform monthly internal checks
- Complete annual expert inspections
- Control repairs and layout changes
If you skip Step 1, the system cannot be considered compliant.
5. Common Misconceptions in Ontario Warehouses
Here are the most common misunderstandings we see during site visits. These issues often lead to non compliance.
- We had a PSR once. If your layout changed, the PSR no longer applies.
- Used racking is grandfathered. Ontario does not apply grandfathering to racking.
- The installer gave drawings. Drawings are not certification.
- Our annual inspection means we are compliant. Certification must come first.
- We will handle this if MOL shows up. The law requires certification before use.
6. Quick Comparison Table
| Requirement | PSR | PSR Exemption | Annual Inspection |
|---|---|---|---|
| Purpose | Certify design and installation | Certify design without a full PSR | Assess condition during use |
| Who performs it | Ontario P.Eng | P.Eng with manufacturer documentation | Competent staff and expert inspector |
| When required | Before use | Before use | Monthly and annually |
| Covers design | Yes | Yes | No |
| Covers condition | Partially | Partially | Yes |
| Trigger | New or changed racking | ANSI compliant systems | All in service systems |
| Common misuse | Treated as permanent | Reused incorrectly | Treated as certification |
